Unfortunately, it doesn't help. 

I tried a docker container with installed CUDA SDK with following commands:

cmake -G Ninja -S llvm -B offload-build -C offload/cmake/caches/Offload.cmake -DLLVM_INCLUDE_TESTS=ON -DOFFLOAD_INCLUDE_TESTS=ON -DLIBOMPTARGET_FORCE_NVIDIA_TESTS=ON
ninja -C offload-build check-openmp

Still see no failures. Considering that `check-libomptarget` target doesn't exist, I suspect there still some differences in envonment.

I think the best course of actions is to avoid sharing the functionality between `clagn-sycl-linker` and `clang-nvlink-wrapper`.
